Yes noted, the fastest way to spread information or create awareness is through social media. Once it's posted, it goes viral and this can help too in the case of bitcoin but then there should be ways to reach out to those who are in remote villages, those without any digital asset or who can't access the internet.
Do you see how contradicting that is? They do not have access to the internet what use would they have of bitcoin then? They won’t even get to use it as a currency. How would they even buy it in the first place?
In my opinion, I will suggest we speak or teach anywhere we find ourselves and to anyone who cares to learn, the use of local radio, flyers, newspaper etc.
Do people still use those traditional media platforms? Probably those who do will not care about bitcoin at all.
